/a/, I'm having a serious conflict here. I was really enjoying this anime, and really looking forward to continuing it, but there's just one monstrous hole in the whole scheme that's ruining the whole thing for me.

It's year 5000 and something; there are colonies all over the galaxy ffs. Half of the shit that's happened has been due to misunderstandings and poor communication between the characters. Why the fuck do aristocrats (rich fuckers) in year 5XXX not have fucking cellphones?

God, the guy gets turned away at the door to his fiancée's house, and just gives up. Call her, you dumbass. This is ruining the show for me, wtf.

See, that's just silly. They're too convenient to become obsolete. It's almost something where they should have thought up some bullshit reason, just to explain why it's possible to have faster than light travel but no mobile phones.

Normally I'd brush this off, but the whole scheme could have been thwarted if the characters had been able to talk freely, which, given the year, and the level of technology that's obviously present, really shouldn't have been an issue. I'm all for 'just as planned', but it has to be somewhat believable.

On some occasions it may be true that cell phones are a type of plot hole, but in cases where the character is secluded it's not hard to imagine that in that time the blocking is much sronger so there would be no chance of reaching her
